Mac Ctrl button no longer provides menu for new tab option, etc., when clicking on links

Mac mini4,1, 2.4 GHz, OS X 10.10.5, latest Firefox version.

For the past few weeks when I click on links while holding down the control button, the drop down menu no longer provides the options it used to (and is an entirely different drop down menu). I can't remember all the options it gave anymore, but the two I used constantly were "Open Link In New Tab" and "Open Link In New Private Window" (I'm paraphrasing from memory but that's close). The "new" drop down menu provides options for  • Share This page;  • Save Page As...;  • Save Page as Pocket and some others (which don't seem very relevant for a link opening).

Anyway, I'd like the former menu back, if possible, and have no idea what I might have done to lose it. My best guesses are that there's some setting in Firefox that got changed (by stray electrons, or because a new version of Firefox changed the default behavior maybe?); or some setting in my computer that got changed. Anyone have any suggestions? Oh, I'm aware that clicking on a link while holding down the Cmd button opens up a new tab, but I want the menu back with the option, and also, I don't really want to have to retrain my "muscle memory"/dedicate a new neuron to learning a new format.--72.80.50.155 (talk) 14:25, 1 September 2017 (UTC)

Sidenote: I wanted to thank all the users who contributed to answering my last question here: Akld guy, StuRat and 47.138.161.183.

Yea, it's annoying when they change things without your permission and for no apparent reason. Do you know what else changed about the same time ? New update to Firefox, for example ? StuRat (talk) 22:08, 6 September 2017 (UTC)

Manufacturers of integrated circuits used in smart cards and similar NFC and RFID devices

I want to know what various implementations of security for things like smart cards, key cards, embedded wireless devices, NFC tags, and RFID tags exist. So far, all I know of is MIFARE, which has memory for storing keys and access controls for them and there is a fair amount of information about it. I've tried using various search terms to find other microcontrollers designed for similar purposes, but most results are about NFC or RFID readers. I did stumble upon Nordic Semiconductor's nRF52 series microcontrollers, but it lacks the specialized silicon design that I'm interested in. The chips I'm interested in can be programmable with a small operating system or they can be entirely mask-based like MIFARE, but I want them to have security features that go beyond having a unique identifier or a random number generator. The chips don't have to be limited to use in smart cards, NFC tags, and RFID chips, but it can also include things like, say, a Bluetooth chip that is meant to be programmed and then used in some sort of application-specific way. What lines are out there like this or companies that manufacture them? — Melab±1 ☎ 16:43, 1 September 2017 (UTC)
